Topic: LEDs again............sorry! (Read 1474 times)

Thanks to Singh and his youtube video I found that the bulbs I required are BA9s, but what is the Headlight pilot light code please.And does anyone know a LED code for thr H3 halogen replacement that is not 46mm long, its too long for the light unit!Just to say 2010 C5.

See the post in the Classic section on the BA9S-W vs -W4. I think the pilot bulbs are BA9S-W4, too. I've ordered a bunch of bulbs and the only other size I can find are BA7S and I think those were for the warning indicator bulbs.Bare

I just went to the local AutoZone store and looked at their selection of lightbulbs. They had quite a few BA9 type bulbs .....

some had large glass domes that exceeded 9mm in diameter, some had small spherical bulbs that were the same diameter as the base, and the one I picked had a 9mm diameter tubular glass dome, was rated at 14 volts, and the wattage was higher than the small spherical bulbs.

Whereas the bulbs with the BA9 base and the larger glass domes won't fit in through the bushing for the pilot lamp, the tubular style fits well, and, sticks out into the pre-focus area.

the 14 volt bulbs look a little yellow-ish compared to a 12 volt bulb - but they will last longer and *I* think the warmer light looks "correct" for the classic style. reminiscent of an older 6-volt system.

12 and 14V bulbs and other automotive and aircraft stuff are the same thing.Most of them are just rated by name at the battery power, presumably. The actual electrical systems are 14V as that is what the stuff gets charged and actually are operated by the generator/alternator at the higher voltage. The 12V moniker is for folks that only know there is a 12V battery in the vehicle. Or in the case of some aircraft, 24/28VThe 14V is closer the the real world.Again, no difference in the parts.Bare

They can be. Healthy 12V vehicle systems can run anywhere from 12V to 14.5V. Most auto specific bulbs are labelled 12V as a simple designation, but they're generally designed to handle any voltage that may come from a healthy system. If it's not an automotive specific part it may be labelled with it's actual voltage rating, which would be a bit higher than 12V.

That said, I'd love to get some 14V bulbs for the speedo. I'd like a nostalgic yellow hue to the lights.

H3 were to be for spotlights which I posted about on another thread, but it was suggested that 2x55w halogen spots may be a bit too much for the C5, so I was enquiring as to H3 LEDs and the possibility of H4 LED and use perhaps H3 Halogen........confused? .......I am!

an H4 LED will lower the demand, but, it won't be enough to account for the increase that a pair of 55watt H3's will add.

there are a variety of H3 style LED implementations available, some are totally worthless, and, others have varying sizes depending on the number of LED segments in their design.

If you can define your maximum size parameters I think a trip around eBay will be "enlightening"......
